A protocol for the generation and precise control of the sulfonyl radical from dimethylsulfamoyl chloride was reported. Different kinds of alkyl sulfonates and sulfonamides were efficiently and selectively obtained under redox-neutral conditions by controlling the reactivity of photocatalysts. A mechanism for the generation of sulfamoyl and sulfonate radicals from dimethylsulfamoyl chloride and the followed sulfonation and sulfonamidation were proposed.

Thus, it should be of practical value for the late-stage functionalization of natural products or medicines.

Zhang, Jun;Zheng, Mengmeng;Yan, Jiayan;Deng, Zixin;Zhu, Dongqing;Qu, Xudong research published 《 A Permissive Medium Chain Acyl-CoA Carboxylase Enables the Efficient Biosynthesis of Extender Units for Engineering Polyketide Carbon Scaffolds》, the research content is summarized as follows. The selective incorporation of new-to-nature extender units into polyketide synthesis is a highly effective way to engineer their carbon scaffolds. Currently, most atypical extender units are biosynthesized via reductive carboxylation of α,β-unsaturated thioesters catalyzed by crotonyl-CoA reductase/carboxylases or thioesterification of malonates by malonyl-CoA ligases followed by epimerase catalyzed enantiomerization. In this study, we identified an unusual β-subunit (Arm13) of the acyl-CoA carboxylase (ACCase) from the biosynthesis of armeniaspirols. This β-subunit is permissive to the α- and ε-subunits of propionyl-CoA carboxylase to form a fully active ACCase. Distinct from the other regular ACCases in substrate specificity, this ACCase can directly carboxylate medium chain acyl-CoAs ranging from C6 to C9 either with or without terminal substituents, e.g., alkyne or Ph groups, to produce corresponding alkylmalonyl-CoAs with high catalytic efficiency. By harnessing the power of this ACCase in extender unit biosynthesis, we introduced structural variation into the carbon scaffold of armeniaspirols by feeding corresponding carboxylate precursors. These findings not only enrich the knowledge of the medium chain-specific ACCases but also provide an important biocatalyst for diversifying building blocks, which will greatly facilitate polyketide engineering.
